Abstract

본 발명은 전자레인지의 고주파 누설 차폐장치에 관한 것으로서, 각각의 내,외측판체를 용접하지 않고 한장의 차폐판으로도어를 제작하여 가공공수의 간소화로 원가 절감과 생산성 향상 및 도어의 두께를 얇게 함은 물론 고주파의 누설을 효과적으로 차단하도록 한 것이다.The present invention relates to a high frequency leakage shielding device of a microwave oven, by manufacturing a door with a single shielding plate without welding each inner and outer plate body to reduce the cost and productivity and simplify the thickness of the door by simplifying the processing work Of course, to effectively block the leakage of high frequency.

이와 같은 본 발명은 도어의 주연부를 따라 설치되어 본체의 전면판넬과 접촉되고 일단을 내,외향으로의 다단 절곡하여일정한 폭과 길이를 갖는 대략 구형(矩形)의 쵸크시일을 형성하여 가열실에서 누설되는 X방향, Z방향의 고주파에너지를차단하는 차폐판과; 상기 차폐판의 중앙부에 가열실을 투시하도록 형성된 피어싱부와; 상기 차폐판의 절곡부위에 취부되어 쵸크시일로의 이물질 유입을 방지하는 쵸크커버로 이루어짐으로 달성된다.The present invention is installed along the periphery of the door is in contact with the front panel of the main body and one end is bent inwards and outwards to form a substantially spherical choke seal having a constant width and length to leak from the heating chamber A shielding plate for blocking high frequency energy in the X and Z directions; A piercing portion formed to project a heating chamber in a central portion of the shielding plate; It is achieved by consisting of a choke cover that is attached to the bent portion of the shield plate to prevent foreign matter into the choke seal.
